Engineered at our Wenzhou manufacturing complex, our multi-stage silent cleaning vehicles and battery-powered scrubbers deliver decibel ratings under 62 dB(A) for continuous daytime operations.
Industrial dust collection and commercial vacuum cleaning have shifted decisively from raw motor suction power to whisper-quiet acoustic attenuation, aerodynamic bypass motors, and sub-micron containment.
Traditional high-capacity hoover vacuums generate intrusive high-frequency turbine whine between 78 and 88 dB(A). DIKE integrates internal sound-baffling labyrinths packed with fire-retardant open-cell polyurethane foam and dual Helmholtz resonance chambers that cancel noise waves at 1,000 Hz – 4,000 Hz, reducing operational sound below 58 dB(A) without throttling airflow.
Carbon brush friction is the primary cause of mechanical motor vibration and premature motor breakdown. Our low-noise industrial hoover cleaners leverage digitally controlled brushless DC turbines engineered with dynamic balance grades conforming to ISO 1940 G1.0. This yields over 2,500 hours of maintenance-free suction and 40% thermal dissipation gains.
Acoustic dampening cannot sacrifice vacuum static water lift. DIKE multi-stage filtration pairs a tangential cyclonic separator with automated pulse-jet blowback and ePTFE membrane filters. This captures 99.995% of respirable silica dust, toner particles, and airborne pathogens down to 0.3 micrometers, conforming strictly to EN 1822 certification standards.
All sound pressure testing on DIKE vacuum sweepers and industrial vacuums is conducted within hemi-anechoic sound laboratories across a 10-point microphone hemisphere at an operator ear distance of 1.0 m, guaranteeing realistic operating acoustic readings under full load.
Global procurement directors from commercial property portfolios, automotive manufacturing plants, and healthcare institutions prioritize acoustic optimization to comply with OSHA 29 CFR 1910.95 and EU Directive 2003/10/EC noise regulations.
Five-star hotels, luxury shopping malls, and corporate headquarters demand continuous daytime housekeeping without disturbing guests or executive meetings. Silent hoovers operate below ambient room conversation (52–58 dB(A)), ensuring frictionless cleanliness in lobbies, corridors, and executive suites.
ICU wards, surgical clinics, and pharmaceutical laboratories have zero tolerance for particulate re-exhaust and noise intrusion. DIKE low-decibel systems couple anti-microbial ABS polymer casings with certified ULPA/HEPA exhaust barriers, trapping bacteria while eliminating acoustic distress for recovering patients.
Airborne electrostatic discharge (ESD) and cooling fan vibration are catastrophic in server server rooms. Our static-conductive vacuum hoses (surface resistivity 10⁴–10⁶ Ω) and balanced, low-vibration dampening feet prevent harmonic resonance against sensitive server rack arrays during active data center operation.
Machining composite graphite, titanium shavings, and cooling oil mists necessitates continuous three-phase extraction. DIKE heavy-duty DK-series vacuums feature spark-arresting cyclones, manual or reverse-pulse blowback filter systems, and stainless-steel collection drums that withstand aggressive abrasive particulates.
Educational institutions and public transit complexes require agile, battery-operated units with universal charging protocols. Our lithium-powered sweepers, trikes, and floor scrubbers allow uninterrupted operations during daytime hours without cord-tripping hazards or disruptive engine exhaust.

Founded in 2017 in Wenzhou, Zhejiang, DIKE combines in-house industrial design, rotational mold tooling, robotic CNC sheet metal fabrication, and acoustic anechoic testing under one integrated roof.
Our heavy-duty recovery tanks and sound enclosures are molded from imported linear low-density polyethylene (LLDPE). Wall thicknesses reach 8 mm to naturally absorb high-frequency motor vibrations and resist acidic or alkaline detergent corrosion.
Every vacuum impeller and suction motor undergoes high-speed dynamic balancing before chassis integration. Motors pass a mandatory 4-hour continuous burn-in load test inside specialized burn-in chambers to ensure zero early-stage electronic failure.
Quality control technicians measure static pressure (mbar), volume flow (m³/h), and decibel levels across 1/3-octave bands. Units exceeding predetermined sound power thresholds are routed for dampener realignment and acoustic baffle adjustment.
We provide full OEM/ODM branding, custom chassis coloring, localized control panel languages, and electrical adaptation (110V/60Hz, 220–240V/50Hz, 380V/440V 3-phase, and modular lithium battery BMS) for our overseas distribution partners.
Importing industrial cleaning machinery requires full verification of regional safety directives, electromagnetic compatibility, battery transport regulations, and rapid spare-parts availability.
Our complete machinery lineup adheres to European Union harmonized standards EN 60335-1, EN 60335-2-69 (industrial wet/dry vacuum cleaners), and Low Voltage Directive (LVD) 2014/35/EU. Full technical dossiers and Declarations of Conformity are supplied with tender submissions.
For cordless models like the DK-1810DC and DIKE-510BT, all integrated lithium battery packs are certified under UN 38.3, MSDS, and maritime IMDG code protocols. This prevents port delays and expedites seamless customs clearance across the EU, North America, the Middle East, and Latin America.
To support cross-border fleet operations, DIKE maintains specialized market representation in New Delhi, India (directed by Mr. Harvansh Shandilya), alongside our direct headquarters engineers in Wenzhou, guaranteeing a 24-hour response window on engineering requests and spare parts dispatch.
DIKE's technical engineering department pursues a structured innovation roadmap focused on autonomous robotics, active noise cancellation (ANC), and cloud-connected telemetry.

Expert insights compiled by DIKE senior application engineers addressing acoustic performance, power configuration, tender documentation, and OEM batch lead times.
We separate motor cooling air from particulate working vacuum streams through dedicated bypass blowers, combined with tuned Helmholtz acoustic absorption chambers and high-density LLDPE acoustic body shrouding. This preserves water lift suction (up to 248 mbar) while keeping operating noise down to 58–64 dB(A).
Single-phase vacuums (e.g., DK-221SMC) run on standard 110V/220V power outlets and are ideal for intermittent workshop cleanups, mobile construction sites, and light industrial tasks. Three-phase units (380V/440V, e.g., DK-221FB) utilize side-channel turbine pumps rated for continuous 24/7 duty without thermal overload, engineered for heavy chip collection, cement grinding, and foundry lines.
Autonomous machines like the SC80 excel in standardized, large-scale commercial facilities (airports, logistics hubs, shopping malls) requiring repetitive daily scheduled cleaning cycles. They reduce dedicated cleaning labor costs by up to 65%. Ride-on scrubbers (such as the KNIAHT 1020BT) provide higher tactical flexibility for dynamic manufacturing plants with shifting pallet footprints and heavy intermittent spills.
Because DIKE controls R&D and electrical sub-assembly in-house in Wenzhou, we customize motor windings, power plugs (UK, EU Schuko, US NEMA, AU), supply frequencies (50Hz/60Hz), and voltage ratings (100V, 120V, 220V, 240V, 380V, 415V, 480V). We also integrate CE-compliant switches, IP54/IP55 electrical boxes, and UL-certified battery management systems (BMS).
Fine dust inevitably blinds pleated cartridge filters, dropping airflow. The manual blowback mechanism uses a reverse air diverter lever that instantly routes atmospheric pressure backwards across the cartridge exterior, dislodging the dust cake directly into the collection drum in seconds without disassembling the machine or exposing workers to respirable dust.
Standard production units have an MOQ of 1 to 2 units for evaluation. Full OEM branding projects (custom LLDPE chassis colors, customized silkscreen logos, branded packaging, and translated manuals) typically require a minimum of 10 to 20 units. Average production lead times range from 15 to 25 calendar days from design sign-off to FOB Ningbo/Shanghai delivery.
